COSRX The 6 Peptide Skin Booster

Llevo usando este producto 2 años junto con COSRX Snail Mucin 96% Power Face Serum y ya es un fijo en mi rutina. No sé explicar exactamente qué hace, pero cuando lo dejo unos días noto la piel más apagada. Con él tengo esa sensación de piel limpia, hidratada y con mejor cara. La textura es muy ligera, se absorbe enseguida y no deja nada pegajoso. Después la piel queda más fresca y luminosa, pero sin parecer que llevas una capa de producto encima. Sólo una buena cara y la piel más bonita y cuidada. La formulación me parece muy completa, con péptidos, niacinamida y ácido hialurónico. Para mí es el típico producto que no sabía que necesitaba hasta que empecé a usarlo y llevo 2 años repitiendo... En la foto: en la parte 1 aparece este producto, el COSRX 6X Peptide Collagen Booster. En el 2 está el COSRX Snail Mucin 96% Power Face Serum y en lel 3 aparecen los dos juntos, que son los que uso habitualmente en mi rutina.

Ci tengo a scrivere questa recensione da appassionata di skincare in quanto questo siero/tonico COSRX è entrato della mia top 5 dei prodotti! È nella mia skincare routine da circa 8 mesi. Anticipo che non ha contro ma solo pro: - La texture è acquosa, leggerissima e si assorbe in un istante senza lasciare alcuna sensazione di unto o appiccicoso, quindi adatta per la mia pelle mista. - lo utilizzo subito dopo la detersione, e data la sua consistenza è ideale per essere stratificato con altri prodotti. - Per me la combo peptidi - niacinamide - acido ialuronico è una bomba! - Concentro l’utilizzo soprattutto nella fronte e nelle rughe intorno agli occhi, e con costanza ho trovato un netto miglioramento ( usato quotidianamente). - Il prezzo è assolutamente onesto per il formato e la qualità. - Lo utilizzo mattina e sera, con la differenza che la sera metto sopra una maschera al collagene e la mattina si vede la differenza! Se può essere di aiuto metto una foto per vedere la consistenza!

Siero di consistenza acquosa e leggermente viscosa, perfetto come booster prima della consueta skincare. Idrata la pelle, si assorbe subito e la lascia idratata, fresca e radiosa. L'ho usato anche al posto delle siero nelle giornate più afose e, visto la confezione generosa, anche sul corpo.

I’ve been using this skin booster for a while, and I absolutely love it! It leaves my skin feeling hydrated, smooth, and refreshed, and I’ve noticed my complexion looks healthier and more even over time. The lightweight texture absorbs quickly and layers well with the rest of my skincare routine. The only downside is the bottle. It doesn’t look very nice and feels a bit cheap compared to how amazing the product inside is. I really hope the brand improves the packaging because the formula is truly excellent. Overall, I highly recommend it and will definitely purchase it again.

Korean skin care and red light therapy has changed my life. I got the glass face I didn’t even know I wanted. My skin is naturally between normal and dry. I’ve always opted for more expensive products, thinking they were *better*. Turns out I was wrong. These products are basic, with simple and clean ingredients, come in big bottles that last - and are low cost. With this routine I went from dull and flat to plump, supple, and legit GLOWING. You cannot hide my glow even under makeup. The pictures speak for themselves. This routine has changed my life. I would recommend these products to anyone and everyone (+red light!! That in and of itself had just as much of an impact as all products combined). Morning routine: 1. Red light mask 15 mins 2. COSRX 6 peptide skin booster 3. BYOMA Hydrating milky toner 4. Medicube PDRN pink peptide eye cream 5. Ponds Crema S moisturizer Night routine: 1. Garnier micellar cleansing water 2. Medicube PDRN hydrating gel cleanser 3. Thayers facial toner (rose is best) 4. COSRX 6 peptide skin booster 5. COSRX snail mucin 6. Medicube PDRN pink peptide eye cream 7. COSRX ceramide skin barrier moisturizer

Este producto es maravilloso 🥰

Te deja una piel súper hidratada y muy luminosa

I'm absolutely in love with this COSRX combo. The 6 Peptide Skin Booster has a light texture that absorbs instantly and leaves the skin with a spectacular plump and hydrated effect, preparing the face wonderfully. Combining it with Peptide Collagen Hydrogel patches is another level: they adhere perfectly, refresh the dark circles area immediately and help a lot to reduce inflammation and smooth expression lines. It's my favorite routine to achieve a Korean glow effect and get rid of tired faces in the mornings. Super recommended!

Richtig klasse. Verfeinert das Hautbild, ohne zu fetten. Gut verträglich auch bei hypersensibler Haut, verstopft die Poren nicht und befeuchtet prima. Sehr praktisch ist auch der Druckkopfspender. Empfehle ich gern weiter

Este producto me encantó, disminuye la textura de piel desde el primer día, totalmente la pena, lo compraría una y otra vez. Llevo la mitad del producto y cada gota es una maravilla. Felicidades por tan buen producto.

El producto a llegado bien embalado.Me gusta su textura,es transparente,no pegajosa,se aplica bien y se absorbe bien,dejando la piel muy suave e hidratada.No tiene olor,no pica al aplicarlo.La verdad que me ha gustado en un principio,no es caro y viene bastante producto.Me he animado a cogerlo ya que los productos coreanos están cogiendo mucha fama de ser buenos productos y efectivos y el precio está muy bien.

Desde que empecé a usarlo noté mejoría

Das Produkt ist sehr gut, ich benutze es auf Hals und Dekolleté. Es zieht sehr schnell ein, klebt nicht und hinterlässt ein gutes Gefühl. Kaufe ich wieder. Nach einer Woche sieht man schon einen Effekt. 👍

Turning 40 this month, significant weight loss, a very demanding job on my feet 8-12 hours leading to 60+ hours a week, I have began to hate looking in the mirror. I don’t wear make up often and when I do, it’s eye make up only. I’ve always had beautiful skin and I never felt the need to cover it up. A very tired and aging face. I do tan 2-3 times a week (I know, I know 🥴 being tan helps my self esteem after losing 100lbs) I am beginning to get dark spots along with wrinkles. I did a lot of research and read a lot of reviews adding multiple items to my cart before making a decision. I ordered this toner and a serum. I washed my face really well and opened up the bottle. The formula was thicker than I had anticipated. It went on smooth using a cotton pad. A few pea size pumps is all it took. Gently smoothing into my face. Overall I thought it was a bit pricey for a toner, but 20ish bucks wasn’t too bad, considering I hope it does what it’s supposed to do. I will update if and when I see results.

I've been using this for well over a year and I use it after I get out of the shower in the morning, and at night when I wash my face. It allows for deeper penetration of other skin care products and I've noticed a huge difference in the texture of my skin as well. It is highly effective with no scent. I have a very mild case of rosacea (self diagnosed, lol). But this has made a significant difference in evening my skin tone and getting rid of the redness. I also apply it to my neck and chest area and have noticed a difference as well, in the way my other products work after applying it. Especially products used to lighten any dark spots like freckles etc. I've noticed a HUGE difference in that area. Because I am fair skinned, unfortunately I am prone to freckles since I was younger. So if I go out in the sun, I get sprinkled with freckles on my nose and upper cheeks as well as my chest and shoulders and although I use SPF, I do live in Florida and I've noticed since moving here from the north my skin looks so much worse. But when using this along with some other dark spot remover products it has made a huge difference in the way the products work! It's a very watery consistency but do not put it on a pad like you would for a toner this is not a toner you want it to absorb into your skin as much as possible. It is not thick at all it comes out basically like water and soaks right into your skin with a few light pads give it about a minute and you'll be ready to move on to your next step in your skincare routine. For the price I think the value for your money is excellent! I will never not have this in my skincare routine, two thumbs up and if I had more thumbs I'd give it more! Haha! And five stars, if I could give it more stars I would!

Excelente producto

This cosmetics from this brand are just amazing. i just recommended them, you can trust in the Korean cosmetics are the best.

Excelente producto, hidrata muy bien la piel, súper ligero y ayuda mucho a las líneas de expresión.

This product is accurately described as a toner serum. It has the lightweight, fast-absorbing texture of a toner, but functions more like a treatment serum. Rather than focusing only on hydration, its real strength is how well it prepares the skin and enhances the performance of products applied afterward. With consistent use, I’ve noticed clearer skin, a brighter and more even tone, and gradual improvement in dark spots. The effect is especially noticeable when pairing it with active treatments such as vitamin C serums. How I use it (evening routine): In the evening, I apply a thin layer and gently pat until fully absorbed, then repeat this step 2–4 times, depending on how dry my skin feels that day. Building hydration gradually this way allows the skin to absorb moisture without heaviness and noticeably improves plumpness and overall moisture retention. Once the toner serum is fully absorbed, I apply my treatment serums (such as vitamin C), followed by a moisturizer with enough oil and hydration to seal everything in. Used this way, it clearly improves how well active serums absorb and perform, leaving the skin looking fuller, healthier, and well-hydrated. Morning use: I also use this in the morning, but usually apply just one light layer. It noticeably improves makeup application—foundation goes on more evenly, adheres better, and stays comfortable throughout the day without emphasizing dryness. I hope this review is helpful for anyone deciding whether this fits into their routine.

Serum para mi rutina de skin care, me gusta que es de buen tamaño 150 ml en comparación de los demas Serum que son por lo general de 30 ml.

BEST EVER! Do not sleep on this product. It is the holy grail in my skin care routine. I’ve been using it for over a year now and the value price point is unbeatable. I get about six months use out of one bottle and I use it every morning and every night. It keeps my skin so soft, bouncy, and honestly looking like my teenage skin all over again at 32 years old! The packaging is really cute and minimalistic and you completely get a full bottle of product. I would recommend this to anybody and everybody. It completely controls the sebum I used to get in my T zone area and also has had a great effect on my hormonal acne when I do have breakouts. If it does have a scent, I honestly do not notice it, but after directly smelling it, it does have a lingering freshness to it that is extremely mild. It is just so great you guys if you’re having any doubts, don’t have any doubts. I promise you will not be disappointed in this product!

Sehr flüssig, aber glaube es ist ganz stark dank Ingredienten.

One of the easiest, most lightweight “boosters” I’ve added to my routine and it actually makes a difference. What I LIKE about it: 1) SMOOTHER, MORE REFINED SKIN —Within a couple of weeks, I noticed my texture becoming softer and more even. Those tiny bumps on the forehead and cheeks looked more refined, and makeup sat noticeably better. It gives that “quietly polished” look without being harsh. 2) SIX PEPTIDES FOR FIRMNESS + CLARITY —Peptides can be hit-or-miss, but this blend really helps with plumpness and clarity. My skin feels bouncier and more elastic in the mornings, and there’s a subtle firmness that builds with consistent use. 3) CALMS REDNESS AND BREAKOUT-PRONE AREAS — it’s not just hydrating, it’s soothing. It settled my redness, especially around the nose and jawline, and helped keep hormonal breakouts less inflamed and quicker to heal. 4) EXTREMELY LIGHTWEIGHT, WATER-LIKE TEXTURE —It absorbs instantly. No stickiness, no pilling, and no extra heaviness under other serums. It truly behaves like a “booster,” meaning it layers seamlessly no matter what you pair it with. 5) PLAYS WELL WITH EVERYTHING —Vitamin C? Perfect. Retinol? Smooth. Niacinamide? Easy. It’s one of those rare products that you can slip into any routine without worrying about reactions or overloading the skin. Not CONs really, just worth noting: HYDRATION IS LIGHT —If your skin is very dry, you’ll still need a hydrating serum or moisturiser after this. Think of it as a reinforcing step, not the main hydration source. Overall: A fantastic daily booster for smoother texture, gentle firming, and a healthier-looking complexion. It’s effortless to use, gentle enough for all skin types, and surprisingly effective for such a lightweight formula. Great for anyone wanting to elevate their routine without adding heaviness or irritation. I hope you found this review HELPFUL. Makes reviewing worthwhile. Thank you!

This stuff is amazing! It never makes me break out and my skin feels soft and moisturized. This is my second bottle. My skin looks great and I don’t even use any lotion afterwards.

Ok! This is some great stuff! I looked up in the Yuka app it rated EXCELLENT! 86/100! I also have been using AFTERWORDS the COSRX 5 PDRN, not with a cotton swab, but just with my fingers, and my face looks like it’s literally glowing! I thought my face was greasy at first, and it felt dry (in a good way) soft and moisturized!! I wouldn’t recommend this for breakouts, but I do have hormonal breakouts constantly!! I also use the peach slices snail rescue first and I can honestly say my skin has never looked more flawless!! I also looked up in chat gpt, which also mentioned this was a very great product! It has no scent which is nice!

Absolutely love this as a first layer serum, it contains HA so you can skip that and go straight for this, full of skin loving peptides, so light on the skin, large bottle but lasts absolutely ages, absorbs very fast due to it being watery but this is good as you can then layer thicker serums on top. I’ve spent a fortune on skincare products now I’m 49 and really need to look after my skin now. When you are young a good moisturiser is all that’s needed and possibly this as a first step but as you get older your skin needs more attention and this product ticks all the right boxes. It’s expensive but lasts a long time so if you break it down it’s great value for money. I would love if they added matraxyl into this serum/toner as I’m having to use a separate serum for that afterwards. I’m going to start pairing this with snail mucin and see if it makes a difference but been using a good while now and I can definitely see results, my skin is hydrated and more even tone and looking plumper. With skincare try just adding one new product at a time so you can see the real results. That’s what I did with this product and the results are amazing and worth every penny. Don’t be put off by the watery consistency it just means it absorbs faster. You also don’t need a lot 2 pumps is more than enough (sometimes we see a big bottle and think we need to use a lot but really you don’t. I’ve been using a good while now and there’s still loads left!!! Definitely recommend especially for mature skin. I have sensitive skin and have had no issues whatsoever. It’s one of my go to products now.

Es libero, siento cambios en mi piel, la siento más firme!!

Good product, light, has all the good stuff. Makes my skin glow. Here’s an added bonus: I’ve been rubbing this into my lips for about 2-3 weeks. It has increased my volume quite a bit! I didn’t really want to buy an additional “lip product” so this is working well! Of course I add laneige lip sleeping mask, and/or other lip moisturizer, but they never changed my volume like this!

Gooooooooood!!!!

I have really, really good skin. And I normally use the Cosrx Snail Mucin every day. I love that stuff. BUT as I'm getting older I feel like my skin needs something with a bit more umph. So I gave this a try. I have to say, I actually really like it. It is more watery than the snail mucin - so keep that in mind. I would use this before anything else - even under the snail mucin. It doesn't really have a smell and I feel like my skin really loves this. It feels softer - younger even if it can feel that way. Totally worth giving it a try. Definitely a good value.

Me ha sorprendido muchísimo la calidad de este tónico facial. Por el precio que tiene, sinceramente no esperaba que fuera tan bueno. Se nota la diferencia desde las primeras aplicaciones: deja la piel suave, fresca e hidratada sin sensación pegajosa. De verdad, un producto que vale la pena y que sin dudarlo recomendaría.

Desde que mi madre lo probó, no se lo puede quitar de la ducha. Le fascina lo ligero que es, lo rápido que se absorbe, y cómo su piel queda suave, luminosa y con un “efecto jugoso”. Lo mejor: ese cóctel de 6 péptidos + niacinamida + ácido hialurónico que parece realmente actuar, dando firmeza e hidratación sin sensación pesada. Perfecto para mimarte día tras día.

My skin texture improved in just a few days.

Light weight and a good moisturizing toner . absorb well. Good for oily and acne prone skin.

Llego en buen estado el embalaje completo y sellado el cartón

My skin looks flawless from the first application. I like the fact that it prepares your skin for other serums, so you can combine what fits your needs. Very good size, worth the money.

I love this product! The change is my face is incredible.

This is the largest bottle of a serum (“booster”) I’ve ever seen. That said, I would’ve preferred less, but have it packaged in glass. But regardless, it feels super hydrating, very light and a perfect first step after washing your face.

lightweight, watery, toner-like texture absorbs swiftly, no irritation and my skin is very hydrated and no smell. I LOVE IT!

Works but doesn’t really help unless paired with other products.

Llevo 4 semanas usando el COSRX 6 Peptide Skin Booster a diario antes del sérum/crema. La textura es muy fluida, casi como una esencia, se absorbe en segundos y deja la piel hidratada y elástica sin sensación grasa. En piel madura y sensible (menopausia/premenopausia), se agradece la combinación de péptidos con ácido hialurónico, N-acetilglucosamina (NAG) y aminoácidos: noto la piel más suave, con mejor textura y un plus de confort, especialmente en días de sequedad o tirantez. Pros • Fórmula ligera que no satura ni hace bolitas bajo otros productos. • Aporta hidratación inmediata y ayuda a que la piel se vea más lisa. • Capa “booster”: potencia bien los sérums de tratamiento (retinal/bakuchiol, vitamina C, etc.). • Dosificador práctico y higiénico. Contras • El efecto en firmeza/poros es gradual; no esperes cambios drásticos en pocas semanas. • Puede quedarse corto si buscas una hidratación muy oclusiva (mejor sellar con crema). Cómo me funciona (rutina piel madura) Mañana: limpieza → 6 Peptide Skin Booster → vitamina C → crema → SPF. Noche: limpieza → 6 Peptide → tratamiento (bakuchiol/retinal según días) → crema con ceramidas. Así consigo hidratación sostenida y mejor tolerancia a los activos en una piel más reactiva por cambios hormonales. Conclusión Excelente booster con péptidos para piel madura en menopausia o premenopausia que busca hidratación ligera, mejorar la textura y preparar la piel para el resto de la rutina. No es un lifting exprés, pero sí un imprescindible de base para que todo lo demás funcione mejor. Repetiré.

Empecé usando productos de COSRX con la clásica baba de caracol, y desde ahí quedé encantada con la marca. Poco a poco fui incorporando más productos como el retinol, la crema hidratante y ahora este 6 Peptide Skin Booster, y tengo que decir que en conjunto hacen maravillas. Este serum es muy ligero, se absorbe al instante y deja la piel suave, luminosa y con una hidratación duradera sin sensación grasosa. Me gusta usarlo como primero producto, y siento que prepara muy bien la piel para lo que venga después. Además, no me ha causado irritación y eso es clave porque tengo piel sensible. Si estás empezando a construir tu rutina con productos eficaces y suaves, esta línea de COSRX es un espectáculo. La calidad, los ingredientes y los resultados realmente valen la pena

Ideal como paso en tu rutina de cuidado de la piel, ayuda a hidratar la piel, lo he comprado muchas veces

Tengo quince días usándolo. Tuve una semana fuerte de playa, y mi piel estaba muy deshidratada, le compré porque en algún sitio vi que era de muy buena calidad y es así. Mi piel está muy hidratada, pasé ese proceso de descamación por el fuerte sol de una semana de playa y este Serum me lo hizo más fácil. Mis poros ni se ven, los afina de una manera muy sutil, es muy fluido el serum que puedes colocar luego tu crema hidratante y queda todo totalmente seco sin grumos ni nada. Me lo coloco dos veces al día y estoy encantada por el producto sin duda seguiré usándolo.

This product is incredible! I use it daily in my skincare routine. It has a very liquid consistency, which really refreshes and deeply hydrates my face. The product absorbs super fast, and it also comes with a generous amount, so it lasts a long time!

I hesitated before buying this because of the large size and the fact that it’s Korean skincare — which can feel very different from Western products. But I’m glad I tried it! This serum (or essence, it feels somewhere in between) is quite watery in texture, but not runny like water. It spreads easily and you only need a small amount, so the big bottle will last a long time. However — and this is key — it takes time to absorb. I usually wait 5 to 10 minutes before applying anything on top, otherwise the next layer (like cream) just slides off and the skin doesn’t feel as smooth. But if you wait, the results are absolutely worth it. My skin feels incredibly soft — almost baby-skin level. It hydrates deeply, brightens the tone, and improves texture. It even seems to have a mild evening/brightening effect. No irritation at all on my very sensitive skin. I checked the ingredients on the Yuka app and it scored 100/100 — no harmful or problematic components. There’s no noticeable scent, which I appreciate. The formula may contain some synthetics, but nothing that caused any reactions for me. In short: great value, amazing results, just give it time to do its job. I’m very likely to repurchase once I finish this bottle.

YES! feels like water on your face and leaves your skin feeling great. I use this tones along with the other Cosrx products and I have never been so happy with my skin. I am in my mid 40's and was looking for something to help with my skin elasticity and firmness. I've been using these product for 2 weeks now, twice a day and already see a difference. Very happy! My skin looks healthy and I never use any foundation, just sunscreen after all the other goodies.

Really absorbs into your skin , and leaves your skin not oily ,dry or sticky just glow face hopefully continue using it I’ll see the results.

Lightweight. Smells good. Feels good. Peptides.

I recently tried the COSRX 6x peptide product and absolutely loved them! I’m an Amazon Influencer and a member of the Amazon Associates Program, and I’ve already created several review videos featuring Medicube products. If you’re interested, I would be delighted to receive some of your products to test and review on my Amazon storefront and social media channels. Thank you for your time, and I look forward to hearing from you!
